[Lldb-commits] [PATCH] Fix process's output to stdout/stderr (MI)

[Ilia K]

Hi abidh, clayborg, emaste,

* Add CMIUtilString::Escape/Unescape methods (MI)
* Fix process's output to stdout/stderr (MI):
lldb-mi escapes process's output to show it in the following format:
```
~"..."
```

But previously not all characters were escaped by CMICmnLLDBDebuggerHandleEvents::ConvertPrintfCtrlCodeToString and output of
```
printf("'\n` - it's \\n")
```
looked like:
```
~"'\r\n` - it's \n"
```

This patch fixes it by using CMIUtilString::Escape method and now it looks like:
```
~"\'\r\n\` - it\'s \\n"
```
